To (LZZ whom it may concern.-

Be it known that I, JOSEPH B. FISCHER, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Ice- Markers, of which the following is a specification.

This invention relates to improvements in ice-markers of thatwell-known class intended to be drawn across an ice-field to cut shallow furrows, serving as lines to be followed later by the cutting-plow.

My improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figure 1 is a side elevation of my improved marker, shown as elevated from the ice and resting upon its runners M; Fig. 2, a plan of the same; and Fig. 3, a vertical transverse section of the implement, exhibitingin elevation the inner face of the rear end of one of the cutter-beams and the parts attached thereto.

In the drawings, A represents the cutterbeam of an ice-marker, constructed substantially as usual, and provided with a longitudinal series of cutting-teeth to serve in cutting the furrow-mark; ii, a similar beam placed alongside the first beam and parallel 1 thereto and at adistance thcrefrom corresponding with the predetermined distance apart of the furrow-markings to be made in the ice; C, a pair of stretchers reaching from beam to beam and serving to hold the two beams in proper relationship to each other; 5

D, a clevis common to both beams, whereby a horse or team may pull both beams along the field as one implement and produce two parallel furrow-marks a proper distance apart;

E, an uprighttriangular metallic plate, rigidly I secured at its bottom against one of the cutter-beams at its rear end, there being one of these plates for each of the beams; 11, a pair of handles (like plow-handles) attached to the rear of the implement by being rigidly secured to the front inclined edges of the plates E, one handle being secured against the face 1 of each of the plates; G, a center bar disposed centrally over the implement and journaled in bearings secured to the stretchers C, this center bar being made, preferably, of tubing; H, arms secured to and projecting at right angles from the center bar, one near each end, these arms being formed, preferably, also of tubing for the sake of lightness; J, a guide-blade secured to the outer ends of these 5 5 arms, this blade lying parallel with the cutter-beams and at a distance from the nearest line of cutters equal to the distance between the two lines of cutters, so that if there were three parallel furrows the marking-cutters could seat in two of them while the guide-blade was in the other one, this guide-blade presenting edges symmetrical above and below the arms H, so as to properly engage a marking-furrow upon either side of the implement, according to which side the guide-blade is turned to; K, a handle articulately attached to the rear one of the arms H and reaching upwardly between the two handles, and serving as a means by which the operator may pull the arms and 1 guide-blade upward and tip them over to the other side of the implement; L, a cross-shaft reaching across the implement from beam to beam, and journaled in bearings upon the beams; M, a pair of cam-like runners rigidly 7 5 secured to this shaft, these runners being of such form and dimension that when turned downwardly they will project below the bottom line of the cutting-teeth, the runners being located at substantially the center of length of the lines of teeth; N, a connecting-rod connected with the shaft L and reaching rearwardly, this rod in the exempliticati on illustrated being connected at its forward end to a wrist-pin in one of the runners; O, a handlever pivoted to one of the handles of the implement, its lower end being pivoted to the rear end of the rod N and its upper end proj ecting upwardly into convenient position to be I reached by the attendant; P, a detent attached go to the lever O and provided with a series of notches; Q, arm-rests provided with upwardlyopen bearings and secured to the two cutterbeams in position to be engaged by the arms II; and R, a suital'ily-located bearing for the detent P, adapted to be ei'igaged by any chosen notch of the detent.

The operation of the implement is as follows: A line is laid out across the ice-field and suitthe implement. The implement is then set at one end of this furrow with the guide-blade ably furrowed to receive the guide-blade of in the furrow and with the body of the implement upon that side of the turrow toward the field of ice which is to be marked oil. The runners M. are turned up out of the way. The implement is then drawn across the field, cutting two turniw-marlzs parallel to the initial furrow and l'lttl'illltl with each other, and at a distance from each other re 'iresented by the gage of the implement. Arriving at the opposite end of the tripthe other side of the iield.the operator manipulates the lever and turns the runners en d downwardly, thus supportin the implement centrally upon the runners independent of the cutting -teeth. \Yhile the implement is thus centrally supported upon its runners it is turned pivotally around to face in the other direction, and this without injury to the teeth or danger of any parts catching in the furrows. lle turns the guide-blade over to the other side of the implement and sets the implement so that this guide-blade will engage the final one of the two furrows already made, and with the bod v of the implement still toward the field to be marked ot't'. lle then turns the runners up and again, crosses the lield, thus producing two more furrow-marks, all of. the furrowmarks being, obviously, a uniform distance apart. Instead of turning the runners up entirely out of the way, he may turn them up a certain distance, so that the will term limiting-stops to come in contact with the ice and regulate the depth to which the teeth may cut, choosing the appropriate detent'notch for this purpose.

The plates E, being broadened. at their,

bases and projecting to the rear of the handles, serve at once as attaching devices and as braces for the handles. The two cutterbeams, in conjunction with the guide-blade and its arms resting in the arm-rests Q, form a well-braced structure specially adapted to resist the peculiar-side strains to which markers are subjected when the guide-blade runs in a furrow more or lessehoked by accumulationsof snow or ice. A single-beam marker provided with an overhanging guide-blade cannot be GOllSil'UCtGd, so far as I know, to meet the strains in a satisfactm'y manner.

The implement, which has been intended.

for and described as an ice-marker, obviously presents features adapting it for use for other icc-furrowing purposes-as, for instance, l'ulldepth cutting or plowin I claim as my invention- 1. in an ice-nn'u'ker, the combination, substantially as set forth, of a marker-beam provided with a line of cutting-teeth and a camshaped runner pivoted to such beam at its center of length and adapted to projectbelow the teeth and serve to supportthe implement with the teeth clear of the ice.

2. In an ice-marker, the combination, substantially as set forth, of a cutter-beam provided. with a line of teeth, a cam-shaped runner pivoted to such beam at its center of length and adapted to project below said teeth and support the implement with the teeth clear of the ice, and adetent to serve in 'lixing intermediate positions oi? said runner and cause the runner to act as a limiting-st op for the depth of cutting of the teeth.

3. In an ice-marker, the combination, substantially as set forth, olf a pair of cutterbeams provided with teeth and disposed. parallel to each other and rigidly united together, a center bar journa led in hearings tillppUl'ttti in a central position between the two beams, a pair of arms projecting at right angles to said center bar, aml a double-edged guideblade secured to the outer ends of said arms parallel to said beams and at a distance from the nearestline of teeth equal to the distance from one line of teeth to the other.

4-. In an ice-marker, the combination, substantially as set forth, of a pair of cutterbeams provided with teeth and disposed parallel to each other and rigidly united, armrests Q, secured to said beams, a center bar 'ournaled in bearings supported centrallybetween said beams, arms projecting at right angles over said center bar and adapted to engage said arm-rests, and a double-edged guide-blade secured to the outer ends of said arms.
